July 4, 20223 yr Good afternoon, Does anybody know how to setup the battery wifi to the app on cellphone. The steps in the owners manual not clear. Thanks Ferdie
July 13, 20223 yr Hi Ferdie I have been struggling to find the app on either IOS or Google. Have you been able to get this at least ,and can you perhaps share? Shaun
July 13, 20223 yr Author https://www.cfenergygroup.com/user_manual/ Look under downloads / user manual/ more. You will find the apk file there. Let me know if you get it to work.
July 16, 20223 yr Author I am in contact with the supplier from China. They are busy investigating. Will post when they have an answer. CNBM Solar.
July 20, 20223 yr I finally found the answer to where to find the APK in this thread, thank you so much. I am unable to pick up the wifi name from the manual when pushing the reset button for 7 seconds. Anyone else have this issue as well?
July 21, 20223 yr Author I was at CNBM solar yesterday to help me with my battery wifi. The updated the firmware on my battery but the main problem was the app on the website does not work. They gave me the correct app. Mine is working fine . The process in the manuel to connect phone to battery also not correct. Please contact Owen, Leon or Ryan and ask them to add you to the CFE Support group on Whatsapp. You can ask questions on the group to assist you with anything. Cell number for Owen 084 975 5067 Leon +86 152 9159 5360 Ryan +86 182 1020 2810 CNBM Solar 25 Tsessebe Crescent Randjespark Midrand. Very helpful and friendly.

October 4, 20223 yr Thank you for this information Ferdie, does anybody know what cable to use to connect A cfe 5,1 kw battery to a Growatt spf500tl inverter? Any help appreciated
October 8, 20223 yr Where will I find the serial number on the CFE 5100S? I need it to register for the app! Kiara
October 9, 20223 yr Author Hallo, There should be a printed label with a bar code next to the wifi antenna. The serial should start with 141........SLKOPG.......
November 4, 20223 yr Author Call or Whatsapp Adeline on +86 183 0301 4060 for updates or more information.
December 13, 20223 yr Hi I need help, I am trying to register my battery on the CFE app but is stuck on this part: Manufacturer , I have a Sunsynk inverter but it is not listed.
December 13, 20223 yr Author Cell number for Owen 084 975 5067. They will assist you to configure battery wifi and send you the updated app. If you don't get hold of Owen Whatsapp Adeline on +86 183 0301 4060. She is in China.
December 22, 20223 yr Hi All, I am also stuck with this. Owen's number goes straight to voice mail. I guess if everyone who has this issue calls him, I would not blame him for burning that SIM card! Could anybody who has had success with this just shortly describe the process? That would be very kind and be helpful.
December 22, 20223 yr Author f you don't get hold of Owen Whatsapp Adeline on +86 183 0301 4060. She is in China. i think the closed for the holidays. Mine also stopped communicating. I am reading my battery condition from my inverter. I will also contact him next year. Please contact Adeline from CNBM directly on +86 183 0301 4060 Edited December 28, 20223 yr by Ferdie K
December 31, 20223 yr @Ferdie K - Are you using these batteries with a Voltronic Inverter ? If so, did you manage to get them communicating with the inverter without issues (ie. communicating works but then Warning 60 at random times, this then prompts a low bus voltage error) - running the batteries without the communication cable connected with user defined parameters and no issues
January 6, 20233 yr Hi, for those who have CFE 5100 batteries with a Deye/Sunsynk inverter, do your batteries charge to 100%, then forces the inverter to use battery instead of solar and then drop to +-95% before charging again and using solar again? My inverter is set to use the BMS and not voltages, but you can set the voltages in the background and they are set as follows: Battery float chargee: 53.6 V Battery absorption charge: 55.6 V Battery equalization charge: 55.6 V Is this normal? If not, what can I adjust to prevent this behaviour

If not, what can I adjust to prevent this behaviour Hi, I am using 8KW SunSynk inverter with 2x CFE 5100s batteries (no solar pannels connected yet), the batteries charge to 100%, then the inverter uses the grid & discharges the bateries to +-90%, then charges to 100% and so it goes on, I dont think that this is normal and also trying to figure out what to do to fix it.

Hi @Paul.Ve, spot on what I'm experiencing. I've read some other forum that stated the BMS is what guides the inverter on what and how to handle the battery. So not really sure if there is a solution to be honest.

If not, what can I adjust to prevent this behaviour If you want to use the user defined option - the Dip switches need to be setup to default ie. SW 1 (1 & 2 up) SW 4 (CANL) 5 up SW 5 (CANH) 4 up Bulk Charge 53.8V Float Charge 53.6V Equalization 53.8V Cut off Voltage: 48V PS: ONLY change dip switches when batteries are off. This is what CFE gave to me - cos the BMS communication is erratic on Voltronic Inverters. Edited January 9, 20233 yr by Rosh
